Hi, could anyone help me with this question?

Not really my area, but is there any info missing at the top of the image?

Nope, that's it I'm afraid. My logic was that for the emission spectrum electrons must move down energy levels, but it looks like there's more to it

From a quick nose around, Is guess that you're correct. The letters refer to the subshells

So it should just be as you suggest? However issacphysics isn't playing ball and letting me try the answer so can't say for definite.

Certainly looks confusing... I was expecting to see an example of the emission series so we know whether they're referring to lyman, balmer or pachen transitions. I think I'll contact them to ask what they're looking for in this question. Thanks for having a look at this for me :smile:

I think the numbers are the levels and the letters the subshells. Hence you can work out the wavelengths from the levels. A bit more info on the question would certainly be good.
